Stratified Notes:

The COBB CatBack is a full stainless steel 3" plug and play exhaust system for the Focus ST. It is a straight forward install and the fitment is spot on. The sound is deeper and healthier than stock, and I find it quiet enough to not be obnoxious.

We include a $50 credit towards a Stratified Flash Tune with this purchase!


Part of the COBB Stage 3 Package, their 3" Stainless Steel Dual Tip Cat-Back for the Ford Focus ST is a direct replacement cat-back exhaust that boasts full 304 stainless steel construction, custom inline mufflers, and dual 4" double wall tips, resulting in a drone-free, unique exhaust note. Perfectly tuned out of the box with the Accessport and ready-to-run with easy installation!

  • 3" 304 Stainless Steel
